SolarWinds Inc. has completed its acquisition by Silver Lake Partners and Thoma Bravo LLC, resulting in a new slate of directors for the Austin-based software developer.

The $4.5 billion sale of SolarWinds was finalized Feb. 5, according to a filing with the U.S. Securities & Exchange Commission. Silver Lake, a California-based private equity firm, and Thoma Bravo, a Chicago private equity firm that is one of the country's largest tech investors, spent approximately $2.5 billion in cash on the deal, plus $ 2 billion in debt financing from Goldman Sachs Group Inc. and other lenders.

Former board members who are no longer directors include: Steven Cakebread, chief financial officer of Yext Inc.; Paul Cormier, president of the products and technologies division of Red Hat Inc.; Ellen Siminoff, president and CEO of California educational website Shmoop University; Roger Sippl, founder of Elastic Intelligence Inc., which was acquired by Intuit Inc. in 2013., and managing partner of venture capital firm Sippl Investments LLC; and Lloyd Waterhouse, who was CEO of McGraw-Hill Education from 2012 to 2014.

The board terms of Siminoff and Waterhouse were scheduled to expire last year, Cormier's term was scheduled to expire this year and the terms of Cakebread and Sippl were scheduled to expire in 2017.

Kevin Thompson remains president and CEO of the company and is still on the board.
